SHOE-BURNISHING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 443,330, dated December 23, 1890. Application filed December 21,1898. Serial No. 294,297. (No model.)

To all whom it may concern:

Be it known that I, EMMONS M. PARKHURST,

a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Shoe Burnishing Machines, of' which the following isa specification, reference being had to the drawings which form a part thereof.

The object of my invention is to provide a machine which shall hold a shoe and present the heel thereof to a reciprocating burnisher 111 a manner suitable to cause every part of the heel to be burnished and perform its movements in an automatic manner.

My object is also to provide in such a machine means for properly adjusting the various movements.

In carrying out my invention I provide a suitable reciprocating burnisher, preferably having an elastically-supported burnishing surface or part, and in connection with such a burnisher I provide a shoe support or holder adapted to hold the shoe firmly and present the heel thereof to the burnisher and move it relatively with respect to said burnisher that it may have a rocking vertical and lateral reciprocating motion.

In the drawings, Figure 1 is a front elevation of my improved burnishing-1nachine. Fig. 2 is a detail view showing how the shoe is held and presented to the burnisher. Fig. 3 is a side elevation of the machine, looking toward the right side. Fig. 4 is a plan view of the machine for imparting to the shoe-supporting devices a reciprocating motion. Fig. 5 is a side elevation of my machine, looking toward the left side. Fig. 6 is a sectional elevation of the mechanism for liftingthe shoesupporting devices up to the burnisher. Fig. 7 is a plan viewof the machine. Fig. 8 is an elevation of the heel-supporter. Fig. 9 is a vertical section of the same. Fig. 10 is an end elevation of the burnisher. Fig. 11 is a side elevation of the same. Fig. 12 is a detail plan view showing double cranks for the burnisher, and Fig. 13 is a detail view of the adjusting device for relatively adjusting the reciprocating shoe-support with respect to the burnisher.

1 is the frame of the machine, having a col umn 2, upon which the burnisher proper and its operating mechanism is supported.

3 is a sliding table, having vertical parts 49, in which the shoe-supporting frames 4 and 5 are guided with provision for vertical move ment., These frames 4 and 5 are connected by cross-frames 47. The heel of the shoe is placed on the heel-supporter 7, which is shown in Figs. 8 and' 9. The central part of'said supporter consists of a rubber center 8, projecting beyond the surrounding leather ring 9,so that no part of the heel can be obstructed during the burnishing operation, and also evenly distribute the pressure put. upon the heel while being held by the supporting device. The lip 10 of the supporter 7 catches the front part of the heel and keeps it from slipping during the rocking motion of the shoe. The heel-supporter 7 is attached to a shaft journaled in two bearings 12 and 13 and secured at the end by a nut 14.

The shoe 6 is further secured in its place by a shaft 16, having a claw 17 on the end, which engages with the inside of the sole of the shoe and presses the heel against its supporter. The pressure is applied by a lever 18, turning on a pin 19 and sliding 011 a circular guide 20, which is provided with teeth for locking the lever at any point desired, according to the height of the heel being burnished. On

the pin 19 a small pinion 21 is keyed, the

teeth of which are engaged in grooves or teeth 22 on a thicker part 23,0arrying the shaft 16, for the purpose of making the shaft move or reciprocate as the lever turns.

On the horizontal shafts 11 and 16 are keyed the beveled gears and 24, which engage gear-wheels 25 and 26, respectively, 011 shafts 27 and 28. At the other ends of said shafts other gears 29 and 30 are respectively secured. A horizontal shaft 31 gives the shafts 27 and 28, by the gears 29 and 30, their motion. This shaft 31 is keyed to a spur-gear 32, which is rotated by a gear-segment 38, pivoted at the lower end 34 by a fulcrum or pivot pin 35 to a bracket 36, which is secured to the main frame. In the middle of said gear-segment is a slot 37, to which the connecting-rod 38 is secured. This rod is put in motion by the slide 40, to which it is connected at 39. Bctween pins 41 in the slide is placed a heartshaped cam 4 3, which gives the slide a uniform forward and backward motion or reeiprocation. This cam a l is secured to and driven by a shaft The shaft 2 is driven by a large spur-gear57, which obtains its motion from a pinion 56, secured on shaft 55. Shaft 55 is driven by a belt 7L5 from the driving-shaft at. The speed is reduced in both transmissions, so as to make the. rocking motion to the heel slow.

hen the shoe has been put in place, as shown in Fig. 2, and fastened by the lever 18, the long vertical lever i5 is pressed down in a horizontal position, as shown in dotted lines in Fig. 1. On this lever is secured a projection or piece l6, Figs. 1 and U, which rises up when the lever 45 is moved, so that its end will come even with the dotted lines as, shown in Fig. 1, and thus raises the frame 4:7 and its connections. The vertical pieces it and 5, which are connected by the cross-piccc or frame 47, slide in the upright frames 4.0 of the table 3, and consequently by pushing up the frame 47 the parts i and 5 rise and the heel is lifted up against the burnisher.

Beveled gears 25 and 20 are provided with feathers and the shafts 27 and 28 with grooves, so that the gear-wheels will travel with the frames, and yet in operation are in connection with their shafts.

'hen the lever -15 is pressed down in its horizontal position, the link 51 turns the crank 52, fastened to shaft The turning of said shaft 53 causes the clutch 51- on the shaft 55 to operate and start the machine to give motion to the shoe.

I11 Fig. 6 is shown attached to the shaft 31 a cam 99, which gives the frame i7 and the shoe which it supports short vertical motions or reciprocations. Besides the rocking motion and this short vertical motion the shoe has also a horizontal motion of a length determined by the height of the heel, so that the bu rnisher can operate on the entire heel. This is obtained in the following manner: Shaft 55 is provided with aworm 58, which drives a large worm-wheel 59, giving the vertical shaft 00 a very slow motion. To the upper end of the shaft 00 is secured a heartshaped cam 100, Fig. .4, which makes thepin 61 slide forward and backward horizontally in its bearing 02. To the end 63 of this pin is fastened a lever-link 64-, with a slot 65 in the middle and traveling on a guide-stud (56. This stud 66 is adjustable in the guide 09, and is screwed therein by a nut 70. It is also connectcd to a lever 67, turning on a center 68. By pushing the lever ti? one way or other horizontally the end of the lever-link 64- beyond the stud ()6 will be made longer or shorter and its movements and that of the table 8 will correspondinglyincrease or decrease, and as the stud is stationaryit acts as a guide for the link 6i. The link 71 is connected at one end to the lever-link (5+ and at the other end with the sliding table 3, and will accordingly move the table forward or backward, giving the shoe its required lateral reciprocating motion. The means for adjusting the shoe with reference to burnisher is shown in Fig. 13,in which 72 is a hand-wheel having a screw 73 passing through a bracket 74-, secured to the table 3 or its connections, and this screw is connected to the link 71 by the guide portion By turning the haud'wheel the table may be adjusted without changing the extent of its reciprocations.

The burnisher 50, as shown in Figs. 10 and 11, consists of a piece of steel 70, nicely curved at the bottom and provided above with the slot or jaw 77, in which the upper piece 78 is placed. A pin 79 connects them,and a spring 80 makes the pressure of the piece 7 G elastic. A slot 81. is made in the upper piece 78, which receives a feather in the guide 82 to prevent the burnisher from turning. Nuts at the top of the burnisher determine its length, and a spring 8i gives it provision for a vertical vibration. 85 is a gas-jet pipe whose end 86 is close to the burnisher, Fig. 3, to provide a flame to keep the burnisher warm.

The horizontal motion of the burnisher is obtained by a belt 87, transmitting the power from the driving-shaft 4:4: and increasing the speed to shaft 88. This shaft 88 has two cranks S9, to one of which is attached the connecting-rod 90, and to the other of which is connected the counter-balance 91 of any suitable construction. The rod hasa horizontal arm or cross-head 102, to the end of which are fastened rods 92, guided in guides To the ends of the rods )2 is secured the horizontal cross piece or head 95, to which the burnishcr is secured. It will nowbc seen that as the burnisher 5O rceiprocatcs rapidly the heel of the shoe isfirstthrust up against it by operating the lever 45, and then as the heel rotates back and forth the cam 99 raises and lowers the heel-supporter to insure the retention of the heel in contact with the burnisher simultaneously with this last operation. The cam 4.3 through its connections causes a given rotary motion to the heel under the burnisher, and the cam lOt) induces through its connections a lateral or horizontal reciprocation of the heel-support and all connections.

The burnishcr is elastically supported and well adapted to give in the proper directions to suit the work being done, and the other devices are designed to impart the requisite movements to suit the shape of the heel.

It is evident that the minor details may be greatly modified without departing from my invention. llence I do not limit myself to the details shown.

Having now described my invention, what I desire to secure by Letters Patent is- 1. In a burnishing-maehine, the combiner tion of the longitudinally-reciprocati11g burnisher and laterally-movable heel-support and means for reciprocating said heel-support approximately at right angles to the movement of the burnisher, all substantially as shown and described.
